Изтеглете websocket-server.jar и го добавете към своя класов път.

Има и примерен проект в github, който демонстрира използването на вграден websocket. - person Joakim Erdfelt; 02.10.2014

вече имам websocket-server.jar, работя в OSGi enviromnet и всички свързани с кея буркани са заредени. Бих искал само да отбележа, че манифестният файл на websocket-servlet.jar има DynamicImport-Package: org.eclipse.jetty.websocket.server.*;version=9 .2 и WebSocketServerFactory присъства в org.eclipse.jetty.websocket.server . така че този клас не е зареден - person maddymishra; 02.10.2014

Бих искал да отбележа, че този проблем ще възникне само в OSGi среда - person maddymishra; 02.10.2014
